Holter ECG recording
Brief summary
Collection of Holter surface ECGs for the development of new sensing and detection algorithms
Detailed description
The aim of the study is to collect data from surface ECGs by using Holter ECG recordings from patients with different forms of diagnosed arrhythmias and/or specific ECG characteristics from heart diseases to support the development of new sensing and detection algorithms for implants.
Interventions
3-channel Holter ECG recording for patients undergoing an EPS
12-channel Holter ECG recording for patients undergoing a routine follow-up

Outcome results
Number of Successful ECG Recordings Per Condition
All ECG recordings were evaluated by an internal board and all patients were allocated to one of 15 groups (covering 14 ECG patterns of interest and one group for no ECG pattern of interest recorded).
Time frame: 24 hours
Population: According to the statistical analysis plan it was pre-specified to report the number of successful Holter recordings per ECG pattern for all patients irrespective of the method for Holter recording.
